Look hot at the beach this summer with these mermaid dangle belly button rings. An antique silver seductive mermaid sits before a striking, vibrant shell in your choice of 5 iridescent colors sure to catch the light. These are natural shells, ensuring that no two are exactly alike. The front is bright and shiny, while the back is rough and organic, cute but not too long. There is even a faceted crystal in matching color sitting atop the shell. From the Etsy shop, SweetLobes, get one in each color for every day of the beach (and every color of swimsuit you own!).
